Catching a roof leak early is great, but preventing one altogether? Even better. Whether you’re deep into a repair or just keeping your rig road-ready, these savvy tips can save you money, time, and a whole lot of frustration down the road.

• Use a FLIR Camera or UV Flashlight After Dark: Hidden pinholes and hairline cracks can go unnoticed in daylight but become visible under the right tools. A FLIR camera adapter for your phone is an affordable option that detects temperature differences your eyes can’t. Alternatively, a UV flashlight can make tiny flaws glow, helping you catch issues before they turn into leaks.

   

• Keep an Emergency Roof Repair Kit Onboard: Equip it with essentials like EternaBond tape, RV-specific sealant, nitrile gloves, a can of denatured alcohol, microfiber shop towels, and a putty knife. Proper surface prep is critical for a lasting repair, especially when you’re far from a service center and need to fix storm or impact damage quickly.

   

• Don’t Over-Tighten Screws on Roof-Mounted Gear: Solar panel brackets, vent covers, and racks should be snug but not cranked down. Overtightening can crush rubber gaskets or crack your roof membrane, both of which can invite leaks.

   

• Inspect After Heavy Weather and Travel: Hail, high winds, falling debris, or long drives can damage seals and seams – even without visible tears. Do a quick walk-around after storms and every trip or extended drive. Issues can develop on the road, and without checking, you might never know.

   

• Use a Digital Moisture Meter Inside Your RV: These inexpensive tools can detect hidden water behind walls or under floors, especially around ceiling corners and roof vents. Catching that early can save you from mold remediation later.

   

• Avoid Walking on Unsupported Roof Sections: Some RVs have weight-bearing walkable roofs, but many don’t. If you’re unsure, use a wide board to spread your weight. A misstep could crack the membrane, or worse, punch through plywood weakened by water.

   

• Don’t Ignore Roof Sag: Sagging roofs often indicate structural damage. If you notice sagging, call a pro immediately.

   

• Apply UV Protectant to Roof Surfaces After Each Scrubbing: This helps prevent the sealants from drying out and cracking under constant sun exposure. It can also extend your roof’s lifespan.

   

• Time Your Repairs with Routine Maintenance: If you’re already planning a cleaning, tire check, or tank flush, add a roof inspection and touch-up to the list. Combining maintenance helps you stay on schedule and avoid separate service calls.

   

• Don’t Skimp on Quality Materials: Bargain-bin sealant might save you a few bucks now, but it can cost hundreds in damage later. Stick to trusted RV-specific brands that bond well and stay flexible over time.

   

• Store Your RV with a Breathable Cover: If you’re parked for the season, a well-fitted, breathable RV cover helps block UV rays and keep debris off your roof while preventing trapped moisture, a major cause of mildew and slow leaks.

Photograph Your Roof Before and After Trips: A quick smartphone pic can serve as a helpful “before” picture if you spot damage later. It’s especially useful for insurance claims or manufacturer warranty issues.
